the picker stick and 'frequent replacement is v necessary; and checks ofthe leather strap type stretch and become loose and require frequent adjustment and replacement. l

To obviate these disadvantages I have Adevised a check which provides a rolling impact surface against which the picker stick strikes, with the further advantage that the stick is shifted slightly laterally on impact to increase the rolling friction, and I have provided a resilient end stop for completingthe stoppage of the picker stick, the end rstop being adjustable to obtain the proper amount of resistance to the picker stick movement.

Referring to the drawing, the novel check comprises a base ||Jvof cast iron or other durable byproviding alignedbearing recesses |'|v for yref.v ceiving the ends of the shaft |4\,f-bearing caps |8; being positioned over the shaft ends andthe Referring to the plane `oflfthe base sothat th'efend-stop arrangement I2 is, positioned toextend 'over and` slightly'overhangfthe roller drums. vThe end stop arrangement `illustrated includes a plurality vInediately aftervthe stick l impacts lthe rollerdrums@V thus preventing the; stick from l o'ver-runn'ir'ig `the l drinne 'and becoming wedged or. locked 'agains t return movement.

The base is mounted on the loom race in the path of movement of the picker stick, a preferred mounting including an angle iron 22 which is secured to the lower face of the base by a holdingr bolt 23; the base end 24 of the angle iron is provided with a bolt opening 25 and the base has an elongated bolt slot 26 extending vertically to permit a vertical and an angular setting. The other material, which carries a rollerassembly and '55 end 21 of the angle iron is recessed as indicated at 28 to slidably seat in the correspondingly shaped end 29 of a second angle iron 39, see Fig. 3, the end 2'| having a bolt slot 3| and the end 29 having a bolt opening 32 to receive a holding bolt 33, the slidable seating permitting a vertical adjustment of the base. The other end 34 of the The roller assembly ispreferably mountedv on l new terug. 2,. it wintenctedthatthe side `edge 9 is preferably angularly. disposed'. i

angle iron 3D is provided with suitable openings 35 for attachment to th'e loom race.

The operation of the novel check may now be explained. The angle iron 30 is secured to the loom race in approximately the position to bring the roller drums in line with and directly in the path of movement of the picker stick at the end of its stroke,.thus providing a substantial area gers 20. The impact is a rollingimpact, and the f roller drums force the picker stick slightly laterally so as to provide an increasing rolling resistance to the continued movement of the stick which is brought to a full stop by the yielding resistance of the laminated spring lingers. The adjustable setting permits the check to be mounted, if desired, so that the lateral thrust of the check causes the stick to slidingly engage the side of the loom race r loom frame, to thus partially or completely stop the inward movement of the stick.

Although I have described and illustrated one preferred embodiment of the invention, it is obvious that changes in the size, shape, and material of the parts, and in their relative arrangements, may be made to suit the requirements for different loom types, without departing from the spirit and the scope of the invention asdefined tatable drum having a resilient facing, said base y having means for adjustably securing to a loom, whereby the rotatable drum is positioned to be impacted by the picker stick, and a stop d evice on said base positioned adjacent the rotatable drum and adapted to be engaged by the picker stick subsequent to the impacting of the rotatable drum.

A picker stick check, comprising a base, a roller assembly mounted thereon including a rotatable drum, said base having means for adjustably securing to a loom, whereby the rotatable drum is positioned to be impacted by the picker stick, and a resilient stop device on said base positioned adjacent the rotatable drum and `adapted to be engaged by the picker stick subsequent to the impacting of the rotatable drum.

4. A picker stick check comprising a base having means for adjustable mounting on a loom, a roller assembly comprising a drum rotatably mounted on a shaft, said base having a recess for receiving the lower portion of the drum and bearings for the shaft ends, whereby the upper portion of the drum extends above the base to be impacted by a picker stick, yand a stop device mounted on said base in adjacent alignment to said drum.

A picker stick check comprising a base adapted to be secured to a textile loom in parallel adjacency to the path of movement of the picker stick, a roller drum rotatably secured to said base, the axis of rotation of the roller 4drum being inclined to the path of movement of the picker stick, whereby the drum is progressively impacted by the picker stick at the end of the picker stick stroke, and resilient stop means adapted to engage the picker stick after it has impacted the drum.
